Abstract
Ce procédé est caractérisé en ce qu'il comporte les étapes suivantes: mesure r en continu la valeur du potentiel d'oxydo-réduction du milieu traité, permettant d'actionner ou non les moyens d'aération; au cours des phases d'aération, mesurer la concentration en oxygène et exploiter sa valeur, conjointement avec celles du potentiel d'oxydo-réduction pour: maintenir l'aération si la concentration en oxygène correspond à une plage de consigne ; diminuer l'aération si la concentration en oxygène est supérieure à la plage de consigne et, augmenter l'aération si la concentration en oxygène est inférieure à la plage de consigne et, réaliser une auto adaptation des consignes d'oxygène en comparant, lors de la transition du potentiel d'oxydo - réduction "nitrification partielle/nitrification totale", la concentration réelle en oxygène, avec la plage de consigne du système et en ajustant la valeur de la consigne en fonction du besoin réel en oxygène dudit système.</ SDOAB>
